INTRODUCTION. 


Authority  for  Jnvestujations: 

Tills  vol  nine  contains  the  results  of  How  ineasiireineuts  on  certain

Scope  of  Investigation: 

These  investigations  are  not  complete  nor  do  they  inchule  all  the  river 
system  or  parts  thereof  that  might  purposefully  be  studied.  The  scope 
of  the  work  is  limited  to  that  which  can  be  provided  with  the  appropria- 
tions available.  The  field  covered  and  the  character  of  the  work  are 
believed  to  be  the  best  that  could  be  accomplished  under  the  controlling 
conditions. 

The  investigations  have  been  concentrated  upon  streams  in  the  central 
and  southern  portion  of  the  State  where  water  supply,  prevention  of 
overflow  and  reclamation  of  swamp  land  make  the  strongest  appeal  for 
immediate  study  of  the  problems. 

It  is  essential  that  records  of  stream  flow  shall  be  maintained  during 
a  period  of  years  sufficient  to  cover  all  stages,  in  order  that  within  reason- 
able limits  the  entire  range  of  flow  from  the  absolute  maximum  to  the 
absolute  minimum  may  be  determined.  The  length  of  such  a  period 
manifestly  varies  for  different  streams  and  cannot  be  absolutely  deter- 
mined. Experience  has  shown  that  the  records  should  cover  from  five 
to  ten  years,  or  for  some  streams  twenty  years  or  more,  tlie  limit  being 
determined  by  the  relative  importance  of  the  stream  and  the  inter- 
dependence of  the  results  and  other  long-time  records  on  adjacent 
streams. 

The  records  herein  set  forth  cover  a  period  of  over  two  years  and 
indicate  a  fairly  completed  range  of  flow  from  maximum  to  minimum. 
The  gauging  stations  are  being  maintained  under  the  present  ajDpropria- 
tion  and  the  records  will  be  kept  as  long  as  the  General  Assembly  sees 
fit  to  appropriate  funds  for  the  purpose. 

In  all  engineering  work  there  is  a  point  of  refinement  beyond  which 
it  is  needless  and  wasteful  to  proceed,  and  this  principle  applies  with 
especial  force  to  stream-flow  measurements.  It  is  confidently  believed 
that  with  some  unavoidable  exceptions  the  stream-flow  data  presented 
in  this  publication  are  sufficiently  accurate  for  all  practical  purposes. 

It  must  be'  borne  in  mind,  however,  that  these  records  extend  over  a 
comparatively  short  period  of  time  and  all  persons  are  cautioned  to  use 
the  greatest  care  in  the  utilization  of  such  incomplete  records. 

Purposes  of  the  Worh: 

Among  the  purposes  for  which  the  results  contained  in  this  volume 
are  requisite  are  navigation,  domestic  water  supply,  water  power,  swamp 
and  overflow  land  drainage,  and  flood  prevention.  The  demands  of  all 
these  interests  are  immediate. 

Navigation: 

At  the  general  election  of  Xov.  3,  1908,  the  Constitution  Avas  amended 
by  popular  vote,  and  the  General  Assembly  was  authorized  to  issue  twenty 
million  dollars  in  bonds  for  the  construction  of  a  waterway  from  Joliet, 
111.,  to  Utica,  111.  The  further  extension  of  this  waterway  to  the  Gulf 
is  under  consideration  by  Congress  and  there  is  already  an  eight-foot 


navigation  below  Utica.  With  the  completion  of  the  Lockport-Utica 
link  in  this  waterway  there  will  be  opened  np  through  the  heart  of  the 
State  and  along  its  western  border  550  miles  of  navigable  trunk  line 
waterwa}'.  There  are  also  about  125  miles  of  navigable  waterway  on  the 
Ohio  river  along  the  southern  boundary,  and  the  Wabash  is  navigable 
along  the  eastern  border.  When  the  State  and  federal  governments 
Ijecome  committed  to  a  definite  policy  of  inland  waterway  improvements 
the  development  of  the  tributaries  to  these  trunk  waterways  become  of 
paramount  importance.  It  is  obvious  that  the  determination  of  stream- 
flow  is  necessary  to  the  intelligent  solution  of  the  many  problems 
involved. 

Domestic  ^Yatcr  Stipply: 

The  highest  use  of  water  is  that  of  domestic  supply,  and  while  the 
State  interest  in  this  aspect  of  the  matter  is  less  direct  than  in  the 
aspects  already  named,  this  use  of  water  nevertheless  has  so  broad  a 
significance  with  respect  to  the  general  welfare  that  the  State  govern- 
ment is  ultimately  and  intimately  concerned. 

Waicr  Fouer: 

Tile  time  is  raj)i(lly  approaching  when  the  development  of  tlie  water 
power  of  the  country  will  be  an  economic  necessity.  Our  stock  of  coal 
is  being  rapidly  dejileted  and  the  cost  of  steam  power  is  increasing 
accordingly.  Industry  will  cease  its  growth  if  chea))  power  is  not 
availal)le.  Water  power  is  the  only  avenue  now  open.  When  the  electric 
transmission  of  power  was  acconi])lishe(l  the  relation  of  our  water  powers 
to  economic  conditions  changed  entirely.  Previous  to  the  day  of  electric 
transmission  the  importance  of  a  watci-  power  was  largely  confined  to 
the  joeality  at  which  it  was  generated,  but  it  has  now  heconie  a  public 
utility  in  which  the  individual  citizen  is  vitally  interested. 

There  is  a  great  j)aneity  of  accurate  observation  as  to  the  amount  of 
water  power  available  within  the  State,  and  inasmuch  as  the  amount  of 
water  power  that  may  be  made  available  is  d<'pendent  on  the  flow  of 
rivers,  the  investigation  of  flow  becomes  a  {)rercquisite  in  the  judicial 
management  of  this  source  of  energy. 

There  are  practically  no  water  pf)wer  sites  on  any  of  the  streams  that 
have  been  studied  u[)  to  the  date  of  this  report,  and  studies  and  investi- 
gations shouhl  he  e,\t<'nded  to  cover  those  streams  uj)on  which  there 
are  opportunities  for  the  development  of  water  power. 

l>rfiinaf/c  of  Stcawp  and  (Jvcrfloufd  Lands: 

'J'here  are  approximately  3,000  square  miles  of  land  subject  to  overflow 
along  our  intra-state  streams.  Prohalily  00  per  cent  of  the  bottom  lands 
of  the  State  are  unprotected  or  inadequately  protected  against  floods  and 
it  is  estimated  that  if  they  could  all  he  brought  under  successful  cultiva- 


8 

tion  there  would  be  juUkd  lo  the  I'arm  value  of  the  State  over  one  hundred 
million  dollars.  There  would  also  he  achlitional  benefits  to  be  derived 
from  improved  health  conditions. 

The  study  ol'  run-olf  is  the  first  consideration  in  connection  with 
drainage  projects.  If,  by  the  drainage  of  a  large  area  into  any  particular 
channel,  that  channel  becomes  so  gorged  with  water  which  it  had  not 
hitherto  been  called  upon  to  convey,  that  overflow  conditions  are  created 
in  places  where  previously  the  land  was  not  subject  to  inundation,  then 
drainage  results  merely  in  an  exchange  of  land  values.  '^^Fliis  is  not  the 
purpose  of  drainage  improvement.  By  making  use  of  (he  data  in  this 
report  such  a  contingency  as  mentioned  above  would  he  avoided. 

Flood  Prevention : 

The  damage  from  floods  to  property  and  crops  in  the  Illinois  bottoms 
is  enormous.  Xo  careful  estimate  of  the  monetary  loss  has  been  made, 
owing  to  the  absence  of  comprehensive  data,  but  these  losses  are  not 
merely  local  in  effect.  They  constitute  an  annual  tax  on  the  property 
in  large  areas  of  the  State  which  sliould  be  reduced  in  the  orderly  prog- 
ress of  government. 

It  goes  without  saying  that  any  consideration  of  Hood  prevention  must 
be  based  on  a  thorough  knowledge  of  streani-iiow,  both  in  tlie  contribut- 
ing areas  which  furnish  the  water  and  along  tlie  lowland  I'ivers. 

Publications  : 

The  data  on  stream-flow  collected  by  the  Jllinois  cooperation  appears 
here  in  print  for  the  first  time,  and  the  records  of  most  of  tlie  stations 
discussed  in  this  report  extend  over  a  period  of  more  than  two  years. 

The  order  of  treatment  of  stations  in  each  basin  in  these  papers  is 
downstream.  The  main  stream  of  any  river  is  determined  on  the  basis 
of  drainage  area.  After  all  stations  from  the  source  to  the  mouth  of  the 
main  stem  of  the  river  have  been  given,  the  tributaries  are  taken  up  in 
regular  order  from  source  to  mouth.  The  tributaries  are  treated  the 
same  as  the  main  stream,  all  stations  in  ench  tributary  basin  being  given 
before  taking  up  the  next  one  Ix-low. 

The  studies  and  investigations  of  stream  flow  in  the  State  of  Illinois 
will  be  continued  until  the  appropriation  for  the  current  fiscal  quarter 
is  exhausted.  Their  further  continuance  and  ])ublication  being  dependent 
upon  further  appropriation  and  authority. 

Definition  of  Terms: 

The  volume  of  water  flowing  in  a  stream — the  "run-off"  or  "dis- 
charge"— is  expressed  in  various  terms,  each  of  which  has  become 
associated  with  a  certain  class  of  work.  These  terms  may  be  divided 
into  two  groups:  (1)  Those  which  represent  a  rate  of  flow,  as  second- 
feet,  gallons  per  minute,  miner's  inches,  and  run-off  in  second-feet  per 


square  unk\  and  (2)  thu-sc  wiiith  represent  the  aetual  quantity  of  water. 
as  run-oft'  in  depth  in  inches  and  acre-feet.  They  ma}''  be  defined  as 
follows : 

"Second-foot"  is  an  abbreviation  for  cubic  foot  per  second  and  is  the  rate 
of  discliarge  of  water  flowing  in  a  stream  1  foot  wide,  1  foot  deep,  at  a 
rate  of  1  foot  per  second.  It  is  generally  used  as  a  fundamental  unit  from 
which  others  are  computed  by  the  use  of  the  factors  given  in  the  following 
table  of  equivalents. 

"Gallons  per  minute"  is  generally  used  in  connection  with  pumping  and 
city  water  supply. 

The  "miner's  inch"  is  the  rate  of  discharge  of  water  that  passes  through 
an  orifice  1  inch  square  under  a  head  which  varies  locally.  It  is  commonly 
used  by  miners  and  iirigators  throughout  the  West  and  is  defined  by  statute 
in  each  state  in  which  it  is  used. 

"Second-feet  per  square  mile"  is  the  average  number  of  cubic  feet  of  water 
flowing  per  second  from  each  square  mile  of  area  drained,  on  the  assump- 
tion that  the  run-off  is  distributed  uniformly  both  as  regard.s  time  and  area. 

"Run-off  in  inches"  is  the  depth  to  which  the  drainage  area  would  be 
covered  if  all  the  water  flowing  from  it  in  a  given  period  were  conserved  and 
uniformly  distributed  on  the  surface.  It  is  used  for  comparing  run-off  with 
rainfall,  which  is  usually  expressed  in  depth  in  inches. 

"Acre-foot"  is  equivalent  to  4o,.560  cubic  feet,  and  is  the  quantity  required 
to  cover  an  acre  to  the  depth  of  1  foot.  It  is  commonly  used  in  connection 
with  storage  for  irrigation  work.

In  addition  to  statements  regarding  the  location  and  installation  of

flow,  and  backwater;  also,  lull  iufonnation  regarding  diversions  which 
decrease  the  total  flow  at  the  measuring  section.  Statements  are  also

The  discharge-measurement  table  gives  the  results  of  tlie  discharge

The  table  of  daily  gage  heights  gives  the  daily  fluctuations  of  the 
surface  of  the  river  as  found  from  the  gage  readings  taken  each  day. 
At  most  stations  the  gage  is  read  once  per  day,  eitlier  in  the  morning 
or  in  tiic  evening.  The  gage  height  given  in  the  iabU'  represents  the 
elevation  of  the  surface  of  the  water  above  the  zero  of  the  gage.  All 
gage  heights  during  ice  conditions,  backwater  from  obstructions,  etc., 
are  pu])lishcd  as  recorded,  with  suitable  foot  notes,  'i'he  rating  is  not 
applicable  for  such  ])eriods  unless  the  proper  correction  tu  the  gage 
heights  is  known  and  applied.  Atb'ution  is  called  to  the  fact  that  the 
zero  of  the  gage  is  placed  at  an  ;iiliii  lary  datum  and  has  no  relation  to 
zero  flow  or  the  bottom  of  tin;  river.  In  general,  the  zero  is  located  some- 
what below  tlie  lowest  known  (low.  so  that  ncgalive  readings  shall  not

The  discliarge  measurements  and  gage  heights  are  Hie  base  data  from 
wliirh  the  rating  taldes  and  inonlhly  diseharge  tables  are  eonipnicd. 

The  rating  table  gives  either  directly  or  by  inler|iolution  the  diseharge

the  rpiantity  given  is  the  mean  flow  for  tlie  day  wlien  the  mean  gage

Field   Mriliods    of   Measuring    Stream    Flow: 

There  are  three  distinct  methods  of  determining  the  flow  of  open- 
channel  streams:  (1)  by  measurements  of  slope  and  cross  section  and 
\he  use  of  Chezy's  and  Kutter's  I'orinulas;  (2)  by  means  of  a  weir  or 
dam;  (3)  by  measurements  of  the  velocity  of  the  current  and  of  the 
area  of  the  cross  section.  The  method  chosen  depends  on  the  local 
physical  conditions,  the  degree  of  accuracy  desired,  the  funds  available 
and  the  length  of  time  that  the  record  is  to  be  continued.  The  velocity 
method  has  been  used  exclusively  in  these  determinations  and  a  de- 
scription of  this  method  is  therefore  considered  sufficient. 

Velocily  Metliod: 

Streams  in  general  present  throughout  their  courses  to  a  greater  or 
less  extent  all  conditions  of  permanent,  semi-i)ermanent  and  varying 
conditions  of  flow.  In  accordance  with  the  location  of  the  measuring 
section  with  respect  to  these  physical  conditions,  current-meter  gaging 
stations  may  in  general  be  divided  into  four  classes:  (1)  those  witli  per- 
manent conditions  of  flow;  (2)  those  with  beds  which  change  only  during 
extreme  high  water;  (3)  those  with  beds  which  change  frequently,  but 
which  do  not  cause  a  variation  of  more  than  about  o  per  ceid  of  the 
discharge  curves  from  year  to  year,  and  (4)  those  with  constantly  shift- 
ing beds.  In  determining  the  daily  flow,  different  office  methods  are 
necessary  for  each  class.  The  field  data  on  which  the  determinations 
are  based  and  the  methods  of  collecting  them  arc,  however,  in  general 
the   same. 

Great  care  is  taken  in  the  selection  aiul  equijunent  of  gaging  stations 
for  detennining  discharge  by  velocity  measurements,  in  order  that  the 
data  may  have  the  required  degree  of  accuracy.  They  are  located  as 
far  as  ])ossib]e,  at  such  {joints  that  the  relation  between  gage  height  and 
discharge  will  always  remain  constant  for  any  given  stage.  The  ex- 
perience of  engineers  of  the  geological  survey  has  been  that  permanency 
of  conditions  of  flow  is  the  prime  requisite  of  any  current-meter  gaging 
station  when  maintained  for  several  years,  unless  funds  are  available 
to  cover  all  changes  in  conditions  of  flow.  A  straight,  smooth  section, 
without  cross  currents,  backwatx?r,  boils,  etc.,  at  any  stage,  is  highly  de- 
sirable; but  on  most  streams  it  is  not  attainable,  except  at  the  cost  of 


13 

a  cable  equipment.  Eoiigh  permanent  sections,  if  measurements  are 
proijerl}'  made  bv  experienced  engineers,  taking  measuring  ])oints  at  a 
distance  nynn  of  2  to  o  per  cent,  or  less,  of  a  total  width,  will,  within 
reasonaljle  limits,  yield  better  results  for  a  given  outlay  of  luoney  than 
semi-permanent  or  shifting  sections  with  smooth,  uniform  current.  So 
far  as  possible,  stations  are  located  where  the  l)anks  are  high  and  not 
subject  to  overllow  at  high  stages,  and  out  of  the  influence  of  tril)utary 
streams,  dams,  or  other  artificial  obstructions  wliii  li  might  aU'eet  the 
relation  Ijetween  gage  height  and  discharge. 

A  jrajrinjr  station  consists  essentiallv  of  a  gage  for  deterniininu-  the 
daily  liuctuations  of  stage  of  the  rivei'  and  some  structure  or  apparatus 
from  which  discharge  measurrincnts  arc  made,  usually  a  l)ridge  or 
cable. 

'J'he  two  factors  required  to  determine  the  discharge  of  a  stream  ])ast 
a  section  perpendicular  to  the  mean  direction  of  the  current  are  the 
area  of  the  cross  section  and  the  jiican  \clocity  (if  Ihiw  ni>rmal  to  that 
section. 

In  nmking  a  measurement  with  ;i  current  meter  a  niunber  of  points, 
called  measuring  points,  arc  measured  oil'  above  and  in  the  ])lane  of  the 
measuring  section  at  which  observations  of  dept h  and  velocity  ai'i'  taken. 
'J'lie.^e  points  are  spaced  equally  for  those  parts  of  the  section  wheic  the 
flow  is  uniform  and  smooth  and  are  spaced  uneciually  Un-  oilier  ])arts, 
according  to  the  discretion  and  judgment  of  the  cngiiiee)-.  in  general, 
the  points  should  not  be  s))aec(|  I'nrihcr  apai't  llian  ")  per  ei'Ut  of  llic

The  measuring  ])oints  divi<le  the  total  cross  section  into  elementary 
Btri])S,  at  each  end  of  which  observations  of  (le|illi  and  velocity  are  made. 
The  discharge  of  any  elementary  stiip  is  I  he  product  of  the  average  of 
the  rlejilhs  at  tlw  two  enils  times  the  width  of  the  strip  times  the  average

Two  methods  of  determining  the  vidocitv  of  How  of  a  stream  are  in 
general   use — the  lioat  method   juui    the  current-meter   nietlind. 

'I'be  lloat  method,  with  its  vnrinns  modilicati<ins  of  surface,  sid)- 
siirface  and  tnlte  or  rod  (loats,  is  now  considered  obsolete  in  tin-  nrdinary 
practice  of  the  I'nited  States  (le(dogical  Survey.  The  use  of  this  method 
is  liiidted  to  special  conditions  where  it  is  impracticabli'  to  use  the  cur- 
rent meter,  such  as  in  ])laces  where  large  (piantities  of  ice  fir  debris  which 
may  damage  the  meter  are  flowing  with  tlie  current,  and  for  miscellane- 
ous measurements  or  other  work  wln're  a  high  degree  of  accuracy  is  not 
necessary.  Tube  floats  are  very  satisfactory  for  use  in  canals  with 
regular  l)ottoms  and  even  flow  of  current.  Measurements  by  the  float 
method   are  made  as   follows:    The  velocitv  of   flow   of   the   stream    is 


14 

obtained  by  observing-  the  time  which  it  takes  floats  set  free  at  clitTerent 
points  across  the  stream  to  jiass  l)etween  two  range  lines  about  300  feet 
apart.  The  area  nsed  is  the  mean  value  obtained  from  several  cross  sec- 
tions measured  between  the  two  range  lines.  The  chief  disadvantages  of 
this  method  are  difficulty  in  obtaining  the  correct  value  of  mean  area 
for  the  course  used  and  uncertainty  regarding  the  proper  coefficient 
to  apply  to  the  observed  velocity. 

The  Price  current  meter  is  now  used  almost  to  the  exclusion  of  other 
types  of  meters  by  the  United  States  Geological  Survey  in  the  determin- 
ation of  the  velocity  of  flow  of  water  in  open  channels,  a  use  for  which 
it  is  adapted  under  practically  all  conditions.  Briefiy,  the  meter  con- 
sists of  six  cups  attached  to  a  vertical  shaft  which  revolves  on  a  conical 
hardened  steel  point  when  immersed  in  moving  water.  The  revolu- 
tions are  indicated  electrically.  The  rating,  or  relation  between  the 
velocity  of  the  moving  w^ater  and  the  revolutions  of  the  wheel,  is  de- 
termined for  each  meter  by  drawing  it  through  still  water  for  a  given 
distance  at  different  speeds  and  noting  the  nuinlx'r  of  revolutions  for 
each  run. 

From  these  data  a  rating  table  is  prepared  wliich  gives  the  velocity  per 
second  of  moving  water  for  any  number  of  revolutions  in  a  given  time 
interval.  The  ratio  of  revolutions  jier  second  to  velocity  of  flow  in  feet 
per  second  is  very  nearly  a  constant  for  all  speeds  and  is  approxi- 
mately 0.45. 

Three  classes  of  methods  of  measuring  velocity  with  current  meters 
are  in  general  use — multi])le-point,  single-]ioint.  and  integration. 

The  two  principal  multiple-])oiiit  mctliDils  in  general  use  are  the 
vertical  curve  and  0.2  and  0.8  de])th. 

In  the  vertical  velocity  curve  method  a  series  of  velocity  determina- 
tions are  made  in  each  vertical  at  regular  intervals,  usually  about  10 
to  20  per  cent  of  the  depth  apart.  By  plotting  these  velocities  as  ab- 
scissas and  their  depths  as  ordinates  and  drawing  a  smooth  curve  among 
the  resulting  points,  the  vertical  velocity  curve  is  developed.  This  curve 
shows  gra])]]ically  the  magnitude  and  changes  in  velocity  from  the  sur- 
face to  the  bottom  of  the  strcajn.  The  mean  velocity  in  the  vertical  is 
then  obtained  by  dividing  the  area  l)(niiided  In'  this  velocity  curve  and 
its  axis  by  the  depth.  This  method  of.  obtaining  the  mean  velocity  in 
the  vertical  is  probal)ly  the  best  known,  but  on  account  of  the  length 
of  time  required  to  make  a  complete  measurement,  its  use  is  largely 
limited  to  the  determination  of  coefficients  for  purposes  of  comparison 
and  to  measurements  under  ice. 

In  the  second  multiple-point  ?nctlK)d  the  meter  is  held  successively  at 
0.2  and  O.fS  depth,  and  the  mean  of  tlie  velocities,  at  these  two  ])oints  is 
taken  as  the  rhean  velocity  for  that  vertical.  On  the  assumption  that 
the  vertical  velocity  cur\'e  is  a  common  parabola  with  horizontal  axis, 
the  mean  of  the  velocities  at  0.22  and  0.?y  depth  will  give  (closely)  the 
mean  velocity  in  the  vertical.  xVctual  observations  under  a  wide  range 
of  conditions  show  that  this  multiple-point  method  gives  the  mean 
velocity  very  closely  for  open-water  conditions  and  that  in  a  completed 
measurement  it  seldom  varies  as  much  as  1  per  cent  frf)m  the  value 


15 

given  by  the  vertical  velocity  curve  method.  Moreover,  the  indications 
are  that  it  holds  nearly  as  well  for  ice-covered  rivers.  It  is  very  ex- 
tensively used  in  the  regular  practice  of  the  United  States  Geological 
Survey. 

The  single-point  method  consists  in  holding  the  meter  cither  at  the 
depth  of  the  thread  of  mean  velocity,  or  at  an  arbitrary  depth  for 
which  the  coefficient  for  reducing  to  mean  velocity  has  been  determined 
or  must  be  assumed. 

Extensive  experiments  by  means  of  vertical  velocity  curves  show  that 
the  thread  of  mean  velocity  generally  occurs  between  0.5  and  0.7  total 
depth.  In  general  practice  the  thread  of  mean  velocity  is  considered  to 
be  at  0.6  depth,  and  at  this  ])()int  the  meter  is  held  in  most  of  the 
measurements  made  by  the  single-point  nietliod.  A  hirgo  number  of 
vertical  velocity  curve  measurements,  taken  on  many  streams  and  under 
varying  conditions,  show  that  the  average  coefficient  for  reducing  the 
velocity  obtained  at  0.6  depth  to  mean  velocity  is  practically  unity.  The 
variation  of  the  coefficient  from  unily  in  individnal  cases  is,  however, 
greater  than  in  the  0.2  and  0.8  method,  and  the  general  results  are  not  as 
satisfactory. 

In  the  other  principal  single-point  method  the  meter  is  held  near  the 
surfac<',  usually  1  I'oot  Ijelow,  or  low  enough  to  be  out  of  the  etl'ect  of  the 
wind  or  other  disturbing  inlluenees.  This  is  known  as  the  sub-surface 
method.  The  eoetficient  for  reducing  the  velocity  taken  at  the  sub- 
surface to  th('  mean  has  been  foniid  to  lie  in  general  from  alioiit  0.85 
to  0.95,  depending  on  tlie  stage,  velo(it\  nnd  cliannel  condii  ions.  The 
higher  the  stage  the  larger  tlie  eoenicienl.  The  method  is  es|ie(ially 
ailii|)ted  for  flood  measurements,  or  when  tlie  velocity  is  so  great  that  the 
meter  caji  not  be  kept  in  the  correct  jwsition  for  the  other  methods. 

The  vertical  integration  method  consists  in  moving  the  meter  at  a 
slow,  uniform  s[)eed  from  the  surface  to  the  l)otlom  and  back  again  to 
the  surface  and  noting  the  munl)er  of  revolutions  and  the  time  taken 
in  the  operation.  This  method  has  the  advantages  that  tiie  velocity  at 
each  ]ioint  of  the  vertical  is  measured  twice.  It  is  useful  as  a  check  on 
the  |)oint  methods.  In  using  the  Price  meter  great  care  should  he  taken 
that  the  vertical  movement  of  the  meter  is  not  rapid  enough  to  vitiate  th(> 
accuracy  of  the  resulting  velocity. 

The  determination  of  the  flow  of  an  ice-covered  sticam  is  dilbenlt, 
owing  to  fliversity  and  instability  of  cfinditions  (hiring  the  winter  ])eriod, 
and  als(t  to  lack  of  definite  informaii(»n  in  regard  to  the  laws  of  ilnv  of 
water  under  ice.  The  method  now  employed  is  to  make  frequent  dis- 
clinrge  measurements  during  the  frozen  periods  by  the  0.2  !ind  O.S  ;ind 
the  vertical  velocity  curve  methods,  and  to  keep  an  accurate  record  of  the 
cf)n(litions,  such  as  the  gage  height  to  the  surface  of  the  water  as  it  rises 
in  a  hole  cut  in  the  ice.  and  the  thickness  and  character  of  the  ice. 
From  these  data  an  approximate  estimate  of  the  chiily  flow  can  be  made 
by  constructing  a  rating  curve  (really  a  series  of  curves)  similar  to  that 
used  for  open  channels,  but  considering,  in  addition  to  gage  heights  and 
discharge,  the  varying  thickness  of  ice.

These  are  used  mainly  to  extend  the  discharge  curves  beyond  the  limits 
of  the  plotted  discharge  measurements,  and  for  checking  purposes  to 
avoid  errors  in  the  form  of  the  discharge'  curve  and  to  determine  and 
eliminate  erroneous  measurements. 

For  every  published  rating  table  the  following  assumjitions  are  made 
for  the  period  of  application  of  the  table:  (a)  That  the  discharge 
is  a  function  of  and  increases  gradually  with  the  stage;  (b)  that  the 
discharge  is  the  same  whenever  the  stream  is  at  a  given  stage,  and  hence 
such  changes  in  conditions  of  How  as  may  have  occurred  during  the 
period  of  application  are  either  compensating  or  negligible,  except  that 
the  rating  as  stated  in  the  footnote  of  each  taljle  is  not  applicable  for 
known  conditions  of  ice,  log  jams,  or  othei-  similar  obstructions;  (c) 
that  the  increased  and  decreased  discharge  due  to  change  of  slope  on 
rising  and  falling  stages  is  either  negligilde  or  comi)ensating. 

As  already  stated,  the  gaging  stations  may  1h'  dixided  into  several 
classes,  as  indicated  in  the  following  ])aragraphs: 

The  stations  of  Class  1  rejjresent  the  most  favorable  conditions  for  an 
accurate  rating  and  are  also  the  most  economical  to  maintain.  The 
bed  of  the  .stream  is  usually  com])osed  of  rock  and  is  not  subject  to  the 
deposit  of  sediment  and  loose  material.  This  class  includes  also  many 
stations  located  in  a  pool  below  which  is  a  ]»ei-manent  rocky  rillle  that 
controls  the  flow  like  a  weir.  Provided  the  control  is  sufficiently  high 
and  close  to  the  gage  to  prevent  cut  and  lill  at  the  gaging  ])oint  from 
materially  affecting  the  slope  of  the  water  surface,  the  gage  height  will 
for  all  practical  purjjoses  be  a  true  index  of  the  discharge.  Discharge 
measurements  made  at  such  stations  visually  plot  within  'I  or  3  per  cent 
of  the  mean-discharge  curve  and  the  rating  developed  from  that  curve 
represents  a  very  high  degree  of  accuracy. 

Class  2  is  confined  mainly  to  stations  on  icjugh  mountainou.-  streams 
with  steep  slopes.  The  beds  of  such  streams  are,  as  a  rule,  comparatively 
permanent  during  low  and  medium  stages,  and  when  the  How  is  suffi- 
ciently well  defined  by  an  aderjuate  number  of  discharge  measurements 
before  and  after  each  flood  the  stations  of  this  class  give  nearly  as  good 


17 

results  as  those  of  Class  1.  As  it  is  seldom  possible  to  make  measure- 
ments covering  the  time  of  change  at  flood  stage,  the  assumption  is  often 
made  that  the  curves  before  and  after  the  flood  converged  to  a  common 
point  at  the  highest  gage  height  recorded  during  the  flood.  Hence  the 
only  uncertain  period  occurs  during  the  few  days  of  highest  gage  heights 
covering  the  period  of  actual  change  in  conditions  of  flow. 

Class  3  includes  most  of  the  current-meter  gating  stations  maintained 
bv  the  United  States  Geolooical  Survcv.  If  sutticient  measurements 
could  be  made  at  stations  of  this  class,  results  would  be  obtained  nearly 
equaling  those  of  Class  1,  but  owing  to  the  limited  funds  at  the  disposal 
of  the  Survey  this  is  manifestly  impossible,  nor  is  it  necessary  for  the 
uses  to  which  discharge  data  are  applied.  The  critical  points  are,  as  a 
rule,  at  relatively  high  or  low  stages.  The  percentage  error,  however,  is 
greater  at  low  stages.  Xo  absolute  rule  can  be  laid  down  for  stations 
of  this  class.  Each  rating  curve  must  be  constructed  mainly  on  the 
basis  of  the  measurements  of  the  current  year,  the  engineer  being  guided 
largely  by  the  past  history  of  the  station  and  the  following  general  law : 
If  all  measurements  ever  made  at  a  station  of  this  class  are  plotted  on 
cross-section  paper,  they  will  define  a  mean  curve  which  may  be  called 
a  standard  curve.  Jt  has  been  found  in  practice  that  if,  after  a  change 
caused  by  high  stage,  a  relatively  constant  condition  of  flow  occurs  at 
medium  and  low  stages,  all  measurements  made  after  the  change  will 
plot  on  a  smooth  curve  which  is  practically  ])arall('l  to  the  standard 
curve  with  respect  to  their  ordinates,  or  gage  heights.  This  law  of  the 
parallelism  of  ratings  is  tiie  fundamental  basis  of  all  ratings  and  esti- 
mates at  stations  with  semi-permanent  and  shifting  channels.  It  is  not 
absolutely  correct,  but,  with  few  exceptions,  answers  all  the  practical 
requirements  of  estimates  made  at  low  and  medium  stages  after  a  change 
at  a  high  stage.  This  law  ajtpears  to  hold  equally  true  whether  the 
change  occurs  at  the  measuring  section  ni'  at  some  controlling  point 
below.  The  change  is,  of  course,  fundamentally  duo  to  change  in  the 
channel  caused  by  cut,  or  fill,  or  hotii,  at  and  near  ilic  measuring  section. 
For  all  except  small  streams  the  changes  in  section  usually  ueeur  at  the 
bottom.    The  following  simple,  but  typical,  examples  illustrate  this  law: 

(a)  If  0.5  foot  of  planking  were  to  be  nailed  on  the  bottom  of  a 
well-ratfd  woodon  fluini'  of  rectangular  section  there  would  result,  other 
conditions  of  How  being  equal,  new  curves  of  discharge,  area,  and 
velocity,  each  plotting  0.5  foot  al)Ove  the  original  curves  when  referred 
to  the  original  gage.  In  other  Avords,  this  coiulition  would  be  analogous 
to  a  unil'orni  fill  or  <nt  in  a  river  channel  wliieh  either  reduces  or 
increases  all  three  values  of  discharge,  area,  and  velocity  for  any  gage 
height.     In  practice,  however,  such  ideal  conditions  rarely  exist. 

(b)  In  tlie  case  of  a  cut  or  fill  at  the  measuring  section  there  is  a 
marked  tendencv  toward  decrease  or  increase,  resjH^etively.  of  the  velocity. 
In  other  words,  the  velocity  lias  a  compensating  effeet,  and  if  the  com- 
pensation is  exact  at  all  stflges  the  discharge  at  a  given  stage  will  be  the 
same  under  both  the  new  and  the  old  conditions.

18 

(L)  In  the  case  of  uniforui  (.■liaiige  along  the  crest  of  a  weir  or  rocky 
controlling  point,  the  area  curve  will  remain  the  same  as  before  the 
change,  and  it  can  be  shown  that  here  again  the  change  in  velocity  curve 
is  such  that  it  will  produce  a  new  discharge  curve  essentially  parallel 
to  the  original  discharge  curve  with  respect  to  their  ordinaies. 

Of  course  in  actual  practice  such  simple  changes  of  section  do  not 
occur.  The  changes  are  complicated  and  lack  uniformity,  a  cut  at  one 
place  being  largely  offset  by  a  fill  at  another  and  vice  versa.  If  these 
changes  are  very  radical  and  involve  large  percentage^  of  the  total 
area — as,  for  example,  on  small  streams — tiiere  may  result  a  wide 
departure  from  the  law  of  parallelism  of  ratings.  In  complicated 
changes  of  section  the  corresponding  changes  in  velocity  which  tend  to 
produce  a  new  parallel  discharge  curve  may  interfere  with  each  other 
materially,  causing  eddies,  hoils,  backwater,  and  radical  changes  in 
slope.  In  such  extreme  conditions,  however,  the  measuring  section 
would  more  properly  fall  under  Class  4  and  would  require  very  frequent 
measurements  of  discharge.  Special  stress  is  laid  on  the  fact  that  in 
the  lack  of  other  data  to  the  contrary  the  utilization  of  this  law  will 
yield  the  most  probable  results. 

Slight  changes  at  low  or  medium  stages  of  an  oscillating  character 
are  usually  averaged  by  a  mean  curve  drawn  among  them  parallel  to 
the  standard  curve,  and  if  the  individual  measurements  do  not  vary 
more  than  5  per  cent  from  the  rating  curve  the  results  are  considered 
good  for  stations  of  this  class. 

Class  4  comprises  stations  that  have  soft,  muddy,  or  sandy  beds.  Good 
results  can  be  obtained  from  such  sections  only  by  frequent  discharge 
measurements,  the  frequency  varying  from  a  measurement  every  two 
or  three  weeks  to  a  measurement  every  day,  according  to  the  rate  of 
diurnal  change  in  conditions  of  flow.  These  measurements  are  plotted 
and  a  mean  or  standard  curve  drawn  among  them.  It  is  assumed  that 
there  is  a  different  curve  for  every  day  of  the  year  and  that  this  rating 
is  parallel  to  the  standard  curve  with  respect  to  their  ordinates.  On 
the  day  of  measurement  the  rating  curve  for  that  day  passes  through 
that  measurement.  For  days  between  successive  measurements  it  is 
assumed  that  the  rate  of  change  is  uniform,  and  hence  the  ratings  for 
the  intervening  days  are  equally  spaced  between  the  ratings  passing 
through  the  two  measurements.  This  method  must  be  modified  or  aban- 
doned altogether  under  special  conditions.  Personal  judgment  and  a 
knowledge  of  the  conditions  involved  can  alone  dictate  the  course  to 
pursue  in  such  cases. 

The  computations  have,  as  a  rule,  been  carried  to  three  significant 
figures.  Computation  machines,  Crelle's  tables,  and  the  20-inch  slide 
rule  have  been  generally  used.     All  computations  are  carefully  checked. 

After  the  computations  have  been  completed  they  are  entered  in  tables 
and  carefully  studied  and  intercompared  to  eliminate  or  account  for  all 
gross  errors,  so  far  as  possible.  Missing  periods  are  filled  in,  so  far  as 
is  fcasiblp.  by  means  of  comparison  with  adjacent  streams.    The  attempt

i;  made  to  complete  years  or  periods  of  discharge,  thus  eliminating 
fragmentary  and  disjointed  records.  J'ull  notes  accompanying  such 
estimates  follow  the  monthly  discharge  tables. 

For  most  of  the  stations  estimates  have  been  juadc  of  the  monthly 
discharge  during  frozen  periods.  These  are  based  on  measurements 
under  ice  conditions  wherever  available,  daily  records  of  temperature 
and  precipitation  obtained  from  the  United  States  Weather  Bureau 
climate  and  crop  reports,  observers'  notes  of  conditions,  antl  a  care- 
ful and  thorough  intercomparison  of  results  with  adjacent  streams. 
Although  every  care  possible  is  used  in  making  these  estimates  they 
are  often  very  rough,  the  data  for  some  of  them  being  so  poor  that 
the  estimates  are  liable  to  as  much  as  25  to  50  per  cent  error.  It  is 
believed,  however,  that  estimates  of  this  character  are  belter  than  none 
at  all,  and  serve  the  purpose  of  indicating  in  a  relative  way  the  propor- 
tionate amount  of  flow  during  the  frozen  period.  These  estimates  are, 
as  a  rule,  included  in  the  annual  discharge.  The  large  error  of  the 
individual  months  has  a  relatively  snudl  uJIect  on  the  annual  total,  and 
it  is  for  many  purposes  desirable  to  have  the  yearly  discharge  computed 
even  though  some  error  is  involved  in  doing  so. 

Acrurucy  and  Ilcliahility  of  Field  Data  and  Comparative  Results: 

Practically  all  discharge  measurements  made  under  fair  conditions 
are  well  within  5  per  cent  of  the  true  discharge  at  the  time  of  observa- 
tion. Inasmuch  as  the  errors  of  meter  measurements  are  largely  com- 
pensating, tbc  mean  rating  curve,  when  well  defnied,  is  much  more 
accurate  tlian  the  individual  measurements.  IVumerous  tests  anil  expe- 
riments have  been  made  to  test  the  accuracy  of  current-meter  work, 
'i'hese  show  that  it  compares  very  favorably  with  the  results  from 
standard  weirs,  and,  (twing  to  simplicity  of  methods,  usually  gives  results 
that  are  much  more  reliable  tiian  those  from  stations  at  dams,  where 
uncertainty  regarding  the  coellicient  and  eomplicaled  conditions  of  How 
])revail. 

The  work,  of  course,  is  dependent  on  the  reliability  of  the  observers. 
With  relatively  few  exceptions,  the  observers  perform  their  W(u-k  hon- 
estly. Care  is  taken,  however,  to  watch  them  closely  and  to  iiKjiiire  into 
any  discrepancies.  It  is,  of  course,  obvious  that  one  gage  reading  a  day 
does  not  always  give  the  mean  height  for  that  day.  As  an  almost 
invariable  rule,  however,  errors  from  this  source  are  eompensaling  and 
virtuallv  negligible  in  a  period  of  one  month,  although  a  single  -In^*- 
reading  may,  when  Uiken  i)y  itself,  be  considerably  in  (irror. 

In  order  to  give  engineers  and  others  information  regarding  the 
probable  accuracy  of  the  com|)tited  results,  footnotes  are  added  to  the 
tables  of  daily  discharge  and  an  accuracy  column  is  inserted  in  the 
monthly  discharge  table.  In  th<!  rating  tables,  "well  defined"  indicates 
in  general  that  the  rating  is  probably  accurate  within  5  per  cent;  "fairly 
well  defined"  within  10  per  cent;  "poorly  defined"  or  "approximate," 
within  15  to  25  per  cent.  These  notes  are  very  general  and  are  based 
on  the  plotting  of  the  individual  measurements  with  reference  to  the 
mean  rating  curve. 


20 

The  accuracy  coliunii  in  llic  iiioiitlily-discharge  table  does  not  apply 
to  the  maximum  or  minimum  nor  to  any  individual  day,  but  to  the 
monthly  mean.  It  is  based  on  the  accuracy  of  the  rating,  the  probable 
reliability  of  the  observer,  and  knowledge  of  local  conditions.  In  this 
colunni,  A  indicates  that  the  mean  monthly  flow  is  probably  accurate 
within  5  per  cent;  B,  within  10  per  cent;  C,  within  15  per  cent;  D, 
within  25  per  cent.     Special  conditions  are  covered  by  footnotes. 

Use  of  the  Data: 

It  is  the  policy  of  the  Internal  Improvement  Commission  to  make 
available  for  the  public  the  base  data  which  have  been  collected  in  the 
field  by  the  Survey  engineers,  and  these  data  will  also  be  published  in 
the  Water  Supply  papers  of  the  United  States  Geological  Survey  from 
time  to  time.  This  is  done  for  the  p)urpose  of  giving  to  any  engineer 
the  opportunity  of  examining  the  computed  results  and  of  changing 
and  adjusting  them  as  may  seem  best  to  him.  Although  it  is  believed 
that  the  rating  tables  and  computed  monthly  discharges  are  as  good  as 
the  base  data  up  to  and  including  the  current  year  will  warrant,  it 
should  alwavs  be  borne  in  mind  that  the  additional  data  collected  at 
each  station  from  year  to  year  nearly  always  throw  new  light  on  data 
already  collected  and  published,  and  hence  allow  more  or  less  improve- 
ment in  the  computed  results  of  earlier  years.  It  is,  therefore,  expected 
that  the  engineer  who  makes  serious  use  of  the  data  given  in  these  papers 
will  verify  all  ratings  and  make  such  adjustments  in  earlier  years  as 
may  seem  necessary. 

The  values  in  the  table  of  monthly  discharge  are  so  arranged  as  to- 
give  only  a  general  idea  of  the  conditions  of  flow  at  the  station,  and  it 
is  not  expected  that  they  will  be  used  for  other  than  preliminary  esti- 
mates. This  is  particularly  true  of  the  maximum  and  minimum  figure, 
which,  in  the  very  nature  of  the  method  of  collecting  these  data,  are 
liable  to  large  errors.  The  maximum  value  should  be  increased  consider- 
ably for  many  stations  in  considering  designs  for  spillways,  and  the 
minimum  value  should  be  considered  for  a  group  of,  say,  seven  days 
and  not  for  one  day. 

The  rating  table,  provided  the  engineer  accepts  it,  is  published  pri- 
marily to  allow  him  to  apply  it  directly  to  the  daily  gage  heights  and 
rearrange  the  daily  discharges  in  order  of  magniiudc  or  by  some  other 
method.  The  precipitation  and  temperature  tables  in  the  appendix  of 
climatological  data  are  self  explanatory.

BIG  MUDDY  KIVER. 


Description. 

The  drainage  basin  of  the  Big  Muddy  river  lies  in  southern  Illinois. 
The  river  rises  in  the  northwestern  part  of  Jefferson  county,  flows 
poutli  to  the  town  of  Zeigler,  in  Franklin  county,  thence  it  flows  westward 
to  Murphysboro,  in  Jackson  county,  from  there  it  flows  south  and  empties 
into  the  Mississippi  river  about  forty  miles  above  Cairo,  111.  Below 
Zeigler  the  river  is  extremely  crooked.  The  length  of  the  river  is  about 
100  miles,  not  including  bends.  The  important  tributaries  are  Beaucoup 
creek.  Little  Muddy  river,  Caseys  creek  and  Middle  Fork  creek;  all  these 
tributaries  are  small  and  of  not  much  importance.-  The  total  drainage 
area  is  2,320  square  miles. 

The  drainage  basin  is  elliptical  in  shape  with  a  major  axis  about 
seventy  miles  long  and  a  minor  axis  about  fifty  miles  long.  The  country 
is  level  or  undulating;  the  soil  is  known  as  "mulatto  soil,"  a  yellowish- 
brown  clay.  Winter  wheat  is  the  staple  crop.  The  southeastern  part  is 
underlaid  with  valuable  coal  veins  and  coal  mining  is  carried  on  quite 
extensively.  The  slope  of  the  river  is  small;  its  sources  are  about  710 
feet,  and  its  mouth  is  about  310  feet  above  sea  level.  The  banks  and  bed 
of  the  stream  are  soft  and  insecure. 

There  are  no  forested  areas  in  this  basin  except  occasional  groves  and 
tlie  growth  along  the  banks  of  the  stream. 

The  mean  annual  rainfall  is  about  fort3'-two  inches.  The  winter 
conditions  are  mild ;  ice  does  not  fonn  very  thick,  and,  as  a  rule,  the 
snowfall  is  light  and  does  not  last  long. 

Storage  possibilities  have  not  been  investigated,  but,  owing  to  the 
growing  demand  for  water  in  this  section,  they  should  receive  careful 
attention. 

There  are  no  opportunities  for  power  development  in  this  basin.  The 
stream  is  similar  to  tlio  other  rivers  in  central  and  southern  Illinois  in 
tliat  it  is  subject  to  higli  floods  and  very  low  water.  In  some  localities 
the  high  water  overflows  the  land  on  each  bank  for  two  or  three  miles ; 
some  sections  resemble  a  lake  during  floods.  At  Murphysboro,  said  to 
be  sixty  miles  from  the  Mississippi  following  the  river,  there  is  frequently 
backwater,  and  floods  reach  the  heiglit  of  thirty  feet  above  low  water. 
There  is  a  possibility  of  constructing  a  canal  from  the  Mississippi  to 
the  coal  fields  that  lie"  along  the  Big  Muddy.  It  is  thought  that  only  one 
lock  would  be  necessary.  Canal  construction  would  probably  be  very 
simple,  as  the  country  is  low  and  the  material  to  jx;  excavated  very  soft.

The  following  gaging  stations  are  being  maintained  in  this  basin: 
Big  Muddy  river  at  Cambon,  1908,  1909,  1910. 
Beaucoup  creek  near  Pinckneyville,  1908,  1909,  1910. 

Big  Muddy  Eiver  xear  Cambon,  III. 

This  station  is  located  at  the  C,  B.  &  Q.  Eailroad  bridge,  about  one 
mile  north  of  Cambon  railroad  station  and  about  one  and  one-half  miles 
east  of  Plumfield,  111.  It  was  established  June  16,  1908,  for  obtaining 
data  for  use  in  studying  the  problems  of  drainage,  flood  control  and 
navigation,  also  to  obtain  general  statistical  and  comparative  data. 

The  middle  fork  of  the  Big  Muddy  is  tributary  on  the  left  bank 
aljout  one-fourth  mile  above  the  station;  the  drainage  area  above  the 
section  is  about  735  square  miles. 

The  datum  of  the  gage  has  not  been  rhnugefl :  the  records  are  reliable 
and  accurate.

BeaUCOLI'  C']{EEK  near  PlNCKNEWlLLi;,   1 LL. 

This  station  is  located  at  the  I.  C.  Eailroad  bridge,  about  one  and 
one-half  miles  east  of  Pinekneyville,  111.  It  was  establisiied  June  17, 
1908,  for  the  purpose  of  obtaining  data  for  use  in  studying  drainage 
and  Hood  control  problems,  and  to  obtain  general  statistical  and  com- 
parative data. 

Little  Beaucoup  creek  is  tributary  on  the  left  bank  below  the  gaging 
station,  and  Galum  creek  is  tributary  on  the  right  bank  about  ten  miles 
below  the  station.  The  drainage  area  above  the  section  is  about  227 
square  miles. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation. 
The  records  for  1908  were  fallen  whenever  the  gage  reader  happened  to 
be  in  the  vicinity  of  the  gage.  Except  in  a  few  cases,  fairly  accurate 
results  will  be  obtained  if  the  missing  gage  heights  are  interpolated. 

The  flood  of  1902  reached  a  height  of  about  27.5  feet  on  the  present 
gage.  The  creek  goes  dry  at  times ;  the  water  then  stands  in  pools  near 
the  gage.

Description. 


The  drainage  area  of  tlic  l-]iiil>air;i>  iImi'  lii>  in  llir  soiiiheastern  por- 
tion of  the  State  of  Illinois.  The  river  rises  in  the  eentral  part  of 
(■haiiii)ai«rn  eounty.  near  I'rhana.  tlows  in  a  soutiierly  direction  through 
Doughis,  ("olc's  and  (,'uniljerland  counties  to  tiie  center  of  .lasper  county, 
whence  it  flows  in  a  general  southeasterly  direction  diagonally  across 
.Ias|)(*r  county,  the  southwestern  corner  of  Crawford  county  aud  thence 
acr()ss  Lawrcucc  county  to  its  junction  with  the  \\'al)asli  river  about 
midway  between  \'incennes,  Ind.,  and  St.  l-'raiicisville.  111.  The  rivi-r 
is  e.xtrenieiy  crooked,  long  tortuous  bends  being  luunerous ;  it-  length. 
exclusive  of  the  bends,  is  about  I'i'i  miles.  The  nu)st  ini|ioii;inl  lrilMitar\ 
is  llickorv  creek  or  North  Fork  eri'ek.  which  is  fribnlnrs  liom  ihi'  left 
l)auk  about  two  and  oiie-lialf  niile>  below  St.  Marie.  111.  The  iota) 
drainage  area  is  about  '^,110  s(|uaic  niilo.  0 

The  drainage  basin  i>  long  and  narrow  with  n  length  of  ai)oul  IdU 
miles  and  a  fairly  unifoi-ni  wiillli  ranging  from  1')  to  ii'i  miles.  The 
>urrounding  country  is  level  or  gently  rolling,  with  some  small  hills 
al(»ng  the  river.  The  sources  of  tlie  river  are  about  "t'M)  feet  and  the 
month  about  100  feet  above  sea  level.  In  the  lower  portion  of  tin! 
drainage  basin  in  the  vicinity  of  St.  .Marie  tlu'  soil  is  sandy  along  the 
river,  while  to  the  north  and  west  occurs  the  familiar  black  loam.  To 
the  ea.'<t  the  soil  is  a  light  colored  day,  which  was  formerly  covered  with 
a  heavy  growth  of  "wat4'r  oak."  There  has  been  very  little  drainage  doiu- 
in  the  uplands,  but  the  liottoms  are  drained  to  some  extent. 

There  are  extensive  oil  (ields  in  the  southweslein  p<n-|ion  <d'  (he. 
drainage  basin  west  of  Lawreneeville.  In  the  upjier  portion  of  the 
drainage  area,  in  the  vicinity  of  Oakland,  there  is  a  sandy  red  .<oil  near 
the  rivr-r  and  black  loam  away  from  the  river:  one  mile  from  the  river 
on  either  side  is  jirairie  country.  The  chief  crop  in  the  drainage  basin 
is  corn,  with  some  wheat.  The  over(lf)W  of  the  river  does  a  large  amount 
of  damage  and  inumlates  large  areas  <d'  bottom  land  throughout  the 
entire  length  of  the  riv<'r. 

There  are  no  forested  area.-  in  this  drainage  ba-in.  The  mriin  jinnual 
rainfall  is  about  forty  inches.  The  conditions  rhiring  the  winter  |)eriod 
are  mild,  as  a  rule,  with  snowfall  ext<'nding  over  a  period  of  about  two 
months  and  lasting  only  a  few  days  at  a  time,  fee  in  the  river  averages 
three  or  four  inehe-  for  ubont  ;i  month.     The  storage  possiliilities  have 


43 

not  been  investigated.  There  arc  no  o])i)ortuiiities  for  water  power. 
There  are  no  springs  and  little  or  no  ground-water  storage  to  keep  up 
the  low  water  flow,  and  in  consequence  there  is  little  flow  in  the  river 
during  periods  of  extreme  drought.  During  wet  seasons  the  ground 
becomes  saturated  and  heavy  rains  are  carried  to  the  river  much  more 
rapidly  than  the  stream  can  take  care  of  and  damaging  floods  result. 
Land  drainage  and  flood  control  are  subjects  of  considerable  importance 
in  this  drainage  area,  and  are  being  investigated  at  the  present  time. 

Two  gaging  stations  liave  been  established  and  are  being  maintained 
in  this  drainage  basin : 

Embarras  river  near  Oakland,  III.,  1909,  1910. 

Embarras  river  at  St.  Marie,  111.,  1909,  1910. 

Embarr^vs  Eiver  near  Oakland,  III. 

This  station  is  located  at  the  highway  bridge  known  as  the  "Antiocli 
Bridge,"  about  two  miles  northwest  of  Oakland,  111.,  on  the  county-line 
road  to  Ilindoboro  and  Areola.  It  was  established  Oct.  23,  1909,  for 
the  purpose  of  obtaining  data  for  use  in  studying  water  supply,  drainage 
and  flood  control  problems,  and  al=o  to  obtain  general  statistical  and 
comparative  data. 

Brushy  Fork  creek  is  tributary  from  the  left  bank  aljout  live  miles 
above  the  station.  The  total  drainage  area  above  the  gaging  station  is 
oSo  square  miles. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation  ; 
the  data  are  accurate  and  reliable.  There  was  no  flow  at  tliis  station 
during  a  portion  of  the  summer  of  1908.  The  flood  of  1897  reached  a 
height  of  about  twent^^-four  feet  by  the  present  gage  datum.

KASKASKIA  RIVEK. 


Description. 

This  river  is  also  called  the  Okaw.  The  drainage  area  of  this  stream 
lies  wholly  within  the  State  of  Illinois.  It  rises  in  the  center  of  Cham- 
paign county,  flows  in  a  southwestward  direction  and  empties  into  the 
Mississippi  river  in  Eandolph  county  near  the  city  of  Chester,  111.  It 
is  about  190  miles  in  length,  not  following  the  bends.  The  river  is  very 
crooked  and  its  total  length  is  not  far  from  400  miles.  The  total 
drainage  area  is  5,840  square  miles.  There  are  but  few  tributaries  of 
any  size;  the  most  important  are  Shoal  creek  and  Silver  creek,  which 
are  tributary  from  the  north  at  the  lower  part  of  the  river. 

The  drainage  basin  is  long  and  comparatively  narrow,  the  average 
width  is  about  thirty  miles,  maximum  widtli  about  sixty  miles.  The 
ground  is  low,  level  or  undulating,  and  in  consequence  the  slope  of  the 
river  is  small.  The  sources  of  the  river  are  about  740  feet  and  its  mouth 
about  350  feet  above  sea  level.  The  soil  is  mostly  black  loam.  In  the 
lower  portion  of  the  drainage  area  the  soil  gradually  ehangos  to  a 
yellowish-brown  clay.  Within  twenty  miles  above  Shelbyville  occurs  the 
only  rock  of  any  extent  along  this  stream.  In  this  liftecn  or  twenty- 
mile  section  the  banks  and  bed  are  largely  of  limestone  or  sandstone, 
elsewhere  the  banks  and  bed  aro  mostly  soft  soil  with  some  gravel. 

There  are  no  forested  areas  in  tliis  drainge  basin;  the  annual  rainfall 
is  about  forty  inches.  In  general,  the  winter  conditions  are  mild. 
Opportunities  for  storage  have  not  been  investigated  to  any  extent, 
although  it  is  a  subject  of  considfTable  iinportanrc.  There  are  no  oppor- 
tunities for  water  power  development  of  any  importance  anywhere  along 
the  river.  Owing  to  the  lownesfl  of  the  drainage  area  there  is  little 
opportunity  for  ground-water  storage.  During  wet  weather  the  ground- 
water plane  rises  to  the  surface  of  the  ground  and  the  rains  rim  off 
into  the  streams  very  quickly,  producing  very  sudden  rises  and  floods. 
During  dry  weather,  since  there  is  little  or  no  ground-water  stored,  the 
flow  of  the  stream  becomes  very  small  nnd  in  some  places  dries  up 
entirelv.  The  banks  of  the  river  are  low  and  in  times  of  floods  large 
areas  are  covered  with  water,  delaying  the  planting  of  crops  and  some- 
times destroying  growing  crops.  Storage  possibilities,  land  drainage  and 
flood  control  are  matters  of  considerable  importance  in  this  basin. 


56 


The  following  gaging  stations  have  been  established  and  maintained 
in  this  drainage  basin  : 

Kaskaskia  river  near  Areola,  1908,  1909,  1910. 
Kaskaskia  at  Shelbyville,  1908,  1909,  1910. 
Kaskaskia  at  Vandalia,  1908,  1909,  1910. 
Kaskaskia  at  Carlyle,  1908,  1909,  1910. 
Kaskaskia  at  N'ew  Athens,  1909,  1910. 
Shoal  creek  near  Breese,  1909,  1910. 
Silver  creek  near  Lebanon,  1908,  1909,  1910. 

E1A.SKASKIA   ElVER   NEAR   AkCOLA,    IlL. 

This  station  is  located  at  the  highway  bridge  known  as  the  Bagdad 
bridge,  about  four  miles  west  of  Areola,  111.  It  was  established  April 
11,  1908,  for  the  purpose  of  obtaining  data  for  use  in  studying  drainage, 
flood  protection,  and  storage  problems,  and  also  to  obtain  general  statis- 
tical and  comparative  data. 

Lake  Fork  is  tributary  from  the  west  about  three  or  four  miles  above 
the  gaging  station.  The  drainage  area  above  the  station  is  about  390 
square  miles. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation, 
and  the  records  are  accurate  and  reliable. 

The  river  at  this  point  is  said  to  go  dry  at  times  and  was  dry  for  about 
two  months  in  1908.  The  highwater  of  May,  1908,  reached  a  height  of 
17.3  feet  on  the  gage.  ,

Kaskaskia  Eiver  at  Shelbyville,  III. 

This  station  is  located  at  the  highway  bridge  at  the  edge  of  Shelbyville, 
just  above  the  C.  &  E.  I.  and  Big  Four  Railroad  bridges  and  just  below 
the  pumping  station  of  the  City  Water  Company  of  Shelbyville.  It  was 
established  Feb.  25,  1908,  for  the  purpose  of  collecting  data  for  use  in 
studying  drainage  and  flood  control  problems,  and  to  obtain  general 
statistical  and  comparative  data. 

There  are  no  tributaries  of  any  size  entering  the  stream  near  Shelby- 
ville. The  drainage  area  above  the  gaging  station  is  about  1,030  square 
miles. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation. 
The  gage  heights  may  be  affected  during  high  water  l)y  backwater  caused 
by  the  lodging  of.  drift  at  the  two  railroad  bridges  below  the  gaging 
station.    The  records  are  accurate  and  reliable.

KASKA8KIA  JilVKK  AT   VaNDALIA,    I  I.I,. 

TIlis  sUitiou  is  locaUid  at  the  liigliway  bridge  at  the  east  end  of  Main 
street,  Vandalia,  III.  It  was  established  Feb.  2G,  1908,  lo  ol)lain  data 
for  use  in  .studying  drainage  (incHtions,  llnnd  |irotoction,  levee  conistruc- 
tinn,  and  for  general  htati&tical  and  coniiiaraiive  piirjioses.  No  tribu- 
taries of  any  size  enter  the  river  near  X'andnlin.  Tho  drainage  arwi 
above  this  point  is  about  1,980  square  ndle 

The  river  for  some  miles  above  and  below  \aiidalia  is  leveed  along 
tiie  left  bank.  It  is  elaimed  that  tliese  levees,  by  eonfining  the  floods, 
have  caused  floods  of  unusual  height  on  the  right  side  of  the  river,  and  a 
number  of  law  suits  have  been  instituted  to  recover  damages  to  })roperty 
situated  on  the  rigid  bank.  During  extreme  floods  these  levee?  some- 
times give  way,  thu.<  reducing  the  flood  fl""  •  -dl  ni>.  wjii.r  l.fiw.v.  r. 
eventually  passes  the  L'ajring  section. 


u 

The  datum  of  tlie  gage  has  remained  unchanged  since  its  installation. 
The  records  are  reliahle  and  accurate.

This  station  is  located  at  the  B.  &  O.  S.  W.  Kaiiroad  bridge,  about 
one-fourth  mile  east  of  the  railroad  station  at  Carlyle,  111.  It  was 
establi.'ihed  ilarch  2,  1908,  for  the  purpose  of  obtaining  data  for  use  in 
studying  drainage,  flood  control,  and  water  sup])ly  problems,  and  to 
obtain  general  .'^tatir^tical  and  comparative  data. 

There  are  no  tributaries  of  any  size  for  ten  miles  above  and  below 
this  station.  Shoal  creek  is  tributary  on  the  right  bank  about  fifteen 
miles  below  the  station.  The  drainage  area  above  the  gaging  station  is 
about  2,680  square  miles. 

The  intake  of  the  water  supply  system  of  Carlyle  is  above  the  gaging 
station.  There  is  a  dam  about  31/2  feet  high  about  700  feet  above  the 
section  which  is  used  for  water  supply  purposes.  The  average  amount 
of  water  pumped  is  about  3, .500,000  gallons  every  thirty  days,  and  during 
June,  July  and  August  the  quantity  is  aljout  4,500,000  gallons  every 


83 

thirty  days.  The  outfalls  of  one  section  of  the  city  sewerage  system 
and  some  private  sewers  are  above  the  gaging  station,  so  the  diversion 
is  small. 

The  (hitum  of  the  gage  has  remained  unchanged  since  its  installation; 
the  records  are  accurate  and  relial)le.  The  tiood  of  1882,  which  is  the 
highest  known,  is  said  to  have  reached  a  height  of  ly^  feet  higher 
than  the  flood  of  1908,  or  about  321/2  feet  on  the  present  gage.  The 
stream  never  goes  dry  at  this  point.  Tt  has  l)een  noticed  during  })eriods 
of  low  water  that  the  water  is  hard,  which  fact  indicates  that  the  flow 
is  kept  up  by  s])rings.

A  record  of  rivor  height  at  this  point  from  .Inn.  23,  1907,  to  Oct.  28, 
100!>.  inclusive,  Avas  kept  for  the  New  Athens  -Imirnal  by  C.  J.  Von  Roth 
Holl'v.  The  river  lieiglit  was  taken  on  Wednesday  and  Thnrs(hiy  morn- 
ings of  each  week,  the  river  height  for  Thursday  being  pubhslied  eacli 
Friday  with  the  change  in  twenty-four  hours  as  obtained  from  the  river 
height  of  Wednesday.  This  record  of  stage  was  kept  by  the  Journal 
mainly  for  the  information  of  farmers  living  on  the  west  side  of  the 
river,  who  are  cut  otf  from  reaching  New  Athens  via  the  highway  bridge 
when  the  river  reaches  a  stage  about  thirty  feet.  The  record  is  authentic. 
These  gage  heights  have  been  carefully  reduced  to  the  datum  of  the 
present  gage,  the  maximum  error  is  probably  not  over  0.4  feet.,  the 
lower  tlie  stage  the  greater  the  error.

Shoal  Creek  near  Breese,  111. 

This  station  is  located  at  the  B.  &  0.  S.  W.  Railroad  bridge,  about 
one  and  one-half  miles  east  of  Brcese,  111.  It  was  established  Nov.  5, 
1909,  for  the  purpose  of  obtaining  data  for  use  in  studying  problems 
of  drainage,  flood  control,  water  supply,  and  storage,  and  also  to  obtain 
general  statistical  and  comparative  data. 

Beaver  creek  is  tributary  -on  the  left  bank  about  three  miles  below 
the  section.  The  total  drainage  area  above  the  gaging  station  is  about 
760  square  miles.  The  intake  of  the  pumping  station  of  the  water 
supply  system  of  Breesc  is  nlmut  one-fourth  mile  above  the  gaging 
section. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation ; 
the  records  are  accurate  and  reliable.  The  creek  is  fed  by  springs  and 
has  not  been  known  to  go  dry  at  this  point.  The  flood  of  1007  reached 
a  height  of  about  twenty-two  feet  on  the  present  gage  datum.

SANGAMON  RIVEK. 


Descriptiox. 

The  drainage  l)asin  of  the  Sangamon  river  lies  Avliolly  within  the 
State  of  Illinois.  The  river  rises  in  the  southwestern  part  of  Ford 
county,  flows  southwest  to  Decatur  in  3Iaeon  county,  thence  flows  west- 
ward until  near  Springfield,  thence  it  Hows  northwestward  to  its  junc- 
tion with  Salt  creek  at  the  northern  boundary  line  of  Menard  county, 
thence  it  flows  westward  and  empties  into  the  Illinois  river  at  the 
northern  boundary  of  Cass  county.  S])iMngfit'ld  is  about  twenty  miles 
southwest  of  the  center  of  the  basin.  \\lii(li  is  roughly  a  right  triangle 
in  shape,  with  the  mouth  of  the  river  op])osite  the  vertical:  tlie  drainage 
basin  lies  very  nearly  in  the  center  of  the  State,  The  river  is  about 
180  miles  in  length,  not  including  bends.  The  total  drainage  area  is 
5,410  square  miles.  The  principal  tributtiries  are  Salt  creek  and  South 
fork. 

The  eastern  third  of  the  drainage  basin  is  somcwliat  undulating  and 
elevated,  tlie  rest  of  ibe  basin  is  a  level  ])rairie.  The  soil  is  a  very 
fertile  rich  black  loam,  especially  adapted  lor  raising  corn.  There  are 
coal  mines  in  the  vicinity  of  Springfield.  The  bed  and  banks  of  the 
river  are  soft  and  insecure.  The  slo])e  of  llie  river  is  small,  tlie  elevation 
of  its  source  is  about  7  00  feet  above  sea  level,  its  mouth  is  about  430 
feet.  There  are  ]io  forested  areas  in  Ibis  drainage  basin:  what  little 
timber  there  is  is  in  small  groves  or  along  the  river  banks. 

'J'lie  annual  rainfall  is  about  37  incbes.  Tbe  winter  conditions  are 
mild;  ice  forms  to  some  extent  and  during  scvci'e  winters  attains  con- 
siderable thickness. 

Storage  possibilities  have  not  been  investigated,  although,  as  in  the 
Kaskaskia  basin,  storage  is  of  considerable  interest. 

On  account  of  the  low  slope,  floods,  low  wat<n'  and  lack  of  suitable 
foundations  for  dams,  there  are  no  oppoit unities  for  water  power. 

Owing  to  the  levelness  and  lowness  of  tbe  drainage  area  there  is  very 
little  ground  storage  in  the  basin;  high  water  follows  every  heavy  rain, 
floods  occur  frequently  and  are  of  considerable  duration.  The  banks 
of  the  river  being  low,  large  areas  are  flooded  and  there  are  numerous 
swamp  areas  in  this  basin.  The  drainage  of  these  swamps  and  the 
opening  up  of  channels  so  that  flood  waters  may  have  an  opportunity 
of  returning  quickly  to  the  main  stream  makes  the  study  of  flood 
control  and  drainage  of  considerable  importance.     In  some  places  short 


129 

sections  of  the  main  stream  are  being  straightened  in  an  effort  to 
provide  a  better  channel  so  that  floods  will  quickly  drain  otf  the 
adjacent  land.  Any  improvement  of  this  nature  should  consider  the 
stream  as  a  whole  and  should  be  commenced  at  the  lower  end. 

The  following  gaging  stations  are  being  maintained  in  this  drainage 
basin : 

Sangamon  river  near  Monticello,  1908,  1909,  1910. 

Sangamon  river  at  Kiverton,  1908,  1909,  1910. 

Sangamon  river  near  Oakford,  1909,  1910. 

Sangamon  river  near  Chandlerville,  1908. 

South  fork  near  Taylorville,  1908,  1909,  1910. 

Salt  creek  near  Kenney,  1908,  1909,  1910. 

Saj^tgamon  River  near  Monticello,  III. 

This  station  is  located  at  the  I.  C.  Eailroad  bridge,  about  one-half 
mile  west  of  Monticello,  111.  It  was  established  Feb.  4,  1908,  for  the 
purpose  of  collecting  data  to  be  used  in  studying  drainage,  water 
su])ply,  and  flood  control  problems;  and  also  for  obtaining  general 
statistical  and  comparative  data. 

There  are  no  tributaries  of  any  size  near  this  station;  the  drainage 
area  above  the  section  is  about  550  square  miles. 

The  datum  of  the  gage  has  not  been  changed;  the  records  arc  reliable 
and  accurate.

Tliis  station  is  located  at  the  highway  bfidge  about  three  miles  north- 
east of  Oakford,  111.,  and  about  two  and  one-half  miles  up-stream  from 
the  C,  P.  &  St.  L.  Eailroad  brid^^^e.  It  was  established  Oct.  26,  1909, 
for  the  purpose  of  nbiainin;;  (hita  fnr  use  in  stiulyint;  problems  of 
drainage  and  flood  control,  ;iiid  f<»  obl;iin  gener;il  slalisliciil  ;nid  com- 
parative data. 

Crane  creek  is  tributary  on  the  right  bank  about  one  and  one-fourth 
miles  below,  nnd  Salt  creek  is  tributary  on  the  right  bank  about  si.x 
and  one-fourth  miles  above  the  section.  The  tol;il  flriiinngc  nrca  nbove 
the  gaging  station  is  about  5,000  square- miles. 

This  station  is  on  the  improved  portion  of  the  river,  the  new  channel 
being  straight  for  about  five  miles  above  and  one  and  one-lialf  miles 
below  the  gaging  section.     This  artificial  channel   was  conslnictcd    70 

—10  s  w 


146 

feet  wide  at  the  top  and  is  now  about  140  feet  wide,  so  that  material 
changes  are  liable  to  occur  in  the  gaging  section,  tending  to  cause  a 
variation  in  the  relation  of  discharge  to  gage  height.  The  C,  P.  & 
St.  L.  Railroad  bridge,  two  and  one-half  miles  below  the  section,  is  a 
wooden  trestle  with  numerous  piles  in  the  stream  bed  which  have  a 
decided  tendency  to  obstruct  the  flow  at  high  water,  as  the  trestle  is  at 
an  angle  to  the  current.  Drift  and  ice  lodge  at  this  trestle  and  aU'ect 
the  gage  heights. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation. 
Because  of  the  inaccessibility  of  the  gage  it  has  not  been  possible  to 
obtain  daily  readings,  but  the  records  obtained  are  accurate  and  reliable. 

The  floods  of  February  and  March,  1907,  and  May,  1908,  reached 
a  height  of  about  21  feet  on  the  present  gage  datum.

Salt  Creek  near  Kenxey,  111. 

This  >Tatioii  is  located  at  the  highway  bridge,  aljout  three  miles  west 
of  Kerniey,  111.,  a  short  distance  below  the  Vandalia  Railroad  bridge.  It 
was  established  Feb.  14,  1908,  in  order  to  collect  data  to  be  used  in  the 
study  of  drainage  and  flood  control  problems,  and  to  obtain  data  for 
general  statistical  and  comparative  ])iirposes. 

Ten  ;Mile  creek  is  tributary  on  the  right  bank  about  four  miles  above 
the  gaging  station.  Salt  creek  is  a  tributary  of  the  Sangamon  river. 
The  drainage  area  above  the  section  is  about  459  square  miles. 

The  datum  of  the  gage  has  not  been  changed;  the  records  are  reliable 
and  accurate. 

The  high  water  of  1882  is  said  to  have  been  about  one  or  one  and 
one-half  feet  liigher  than  that  of  the  spring  of  1908,  or  to  have  reached 
a  height  of  about  sixteen  feet  on  the  present  gage.

South  Fork  of  Saxgamon  Eiver  xeau  Taylorville,  III. 

This  station  is  located  at  tlie  Wabash  Kaih'oad  bridge,  about  three 
and  one-half  miles  southwest  of  Taylorville,  111.,  and  about  one-fourth 
mile  up-stream  from  the  highway  bridge  across  the  South  fork  known 
as  the  "Half  Acre  Bridge."'  It  was  established  Feb.  11,  1908,  for  the 
jnirpose  of  obtaining  data  for  use  in  studying  drainage,  flood  control, 
and  water  supply  problems,  and  also  to  obtain  general  statistical  and 
comparative  data. 

Bear  creek,  a  small  tributary,  enters  the  stream  on  the  left  bank  a 
few  miles  below  the  station.  The  drainage  area  above  the  gaging  station 
is  about  437  square  miles. 

In  August,  1909,  a  drainage  ditch  was  dug  along  the  river  in  this 
vicinity,  straightening  the  course  of  the  stream,  but  coinciding  with  the 
original  cbannel  at  the  gaging  station.  The  cross-section  of  the  stream 
at  tlie  gaging  station  was  not  altered,  but  the  relation  between  gage 
height  and  discharge  was  materially  changed,  due  to  the  change  in 
slope.  The  gage  heights  to  Aug.  10,  1909,  inclusive,  refer  to  the  section 
before  the  change.  The  gage  heights  from  Aug.  11  to  Sept.  1,  1909, 
inclusive,  are  of  no  value,  because  the  stream  was  dammed  up  for  purpose 
of  construction  during  that  period.  On  Sept.  2,  1909,  the  datum  of 
the  gage  was  lowered  two  feet,  and  the  gage  heights  from  tliat  date  on 
refer  to  the  new  conditions.  In  all  comparisons  between  the  data  for 
the  original  and  the  new  conditions  it  should  be  noted  that  the  gage 
d}jtum  lias  been  changed.     The  records  are  accurate  and  reliable.

CAHOKIA  CEEEK. 


DllSCRIPTION. 

The  drainage  area  of  Cahokia  creek  lies  in  the  southwestern  part  of 
the  State  of  Illinois.  The  creek  rises  in  the  southern  part  of,  and  about 
on  line  between  Montgomery  and  Macoupin  counties,  Hows  in  a  south- 
westerly direction  diagonally  across  the  southeast  corner  of  Macoupin 
county  and  the  northwest  portion  of  Madison  county,  past  Edwardsville, 
through  East  St.  Louis,  111.,  and  empties  into  the  Mississippi  river.  The 
creek  is  very  crooked  and  its  leuglii  is  a])pro.\imately  lit'ty-iive  miles. 
The  total  drainage  area  is  375  square  miles.  Its  principal  tributary  is 
Indian  creek,  which  enters  from  the  right  bank  about  three-fourths 
of  a  mile  north  of  Die  Wabash  IJailroad  bridge  near  Poag.  111. 

The  di-ainage  basin  is  long  and  narrow,  being  al)0ut  r(iit\-II\c  iiiiU's 
in  length;  the  average  widtli  is  about  eight  miles;  and  maxinium  width 
is  about  twelve  miles.  The  ground  is  low,  level,  nv  undulating,  with  a 
chain  of  bliifl's  r-rossing  the  drainage  area  just  noiili  of  I'oag,  111.  The 
sources  of  the  creek  are  about  G8U  feet,  and  the  mouth  nliDul  ."iS.")  feel 
above  sea  level. 

'i'liere  are  no  forested  areas  in  Ibis  diainage  basin.  Tlic  mean  .innn.il 
rainfall  is  about  forty  inches.  In  genernl,  (he  winler  condilions  are 
mild.  The  o])|iortuniti(.'S  for  sionige  aiul  water  ])ower  (levcl()|)inent  hav(^ 
not  been  invostigaled,  but  arc  umlmilitedly  not  worthy  of  consideration. 
Flood  eontrol,  especially  in  its  relation  to  the  projiosed  flood  protection 
works  of  the  VaxM.  Side  TiCvee  nnd  S;inilary  District  of  V/.\<{  St.  Tjouis,

Tliis  station  is  located  at  tin;  Wabash  I'ailroad  Ijridge,  al)out  threc- 
fourtlis  of  a  mile  nortlicast  of  the  Wabash  Kailroad  station  at  Poag,  111. 
It  was  establi,^hed  Dec.  13,  IHOO,  to  obtain  data  for  use  in  studying 
drainage  and  flood  control  pro])lenis.  The  data  collected  will  be  used 
by  the  East  Side  Ixivee  and  Sanitary  District  of  p]ast  St.  Louis,  111,,  in 
its  study  of  flood  control  and  prevention  at  that  place.

Indian  creek  is  tributary  from  the  right  bank  about  tliroc-rourths  of 
a  mile  above  the  section.  The  total  drainage  area  above  the  gaging 
station  is  259  square  miles,  as  determined  by  the  East  Side  Lovoe  and 
Sanitary  District. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation  ; 
the  records  are  accurate  and  reliable.  The  data  at  present  are  insufficient 
for  a  determination  of  the  daily  flow.

LITTLE  WABASH  EIVEE. 


Description". 


The  drainage  basin  of  the  Little  Wabash  river  lies  in  the  southeastern 
part  of  the  State  of  Illinois.  The  river  rises  in  the  southwestern  corner 
of  Coles  county,  flows  slightly  southeastward  and  empties  into  the  Wabash 
river,  about  fifteen  miles  above  its  mouth,  at  the  boundary  line  between 
White  and  Gallatin  counties.  The  Skillet  fork  is  the  only  tributary  of 
any  size,  joining  it  not  far  from  its  mouth.  The  Little  Wabash  is  about 
150  miles  in  length.    The  total  drainage  area  is  3,2UU  square  miles. 

The  basin  is  shaped  something  like  a  parallelogram  with  the  long  sides 
north  and  south.  The  country  is  level  or  undulating.  The  soil  is  a 
rich  black  loam  in  the  northern  part;  in  the  southern  part  it  gradually 
changes  into  a  yellow  clay  or  "mulatto  soil."  The  elevation  of  the 
sources  of  the  river  is  about  720  feet;  at  its  mouth  it  is  about  340  feet 
above  sea  level.  There  are  no  forested  areas  in  this  basin.  The  annual 
rainfall  is  about  forty-two  inches.  Tlie  wiulci-  conditions  are  mild:  iic 
does  Jiot  form  very  tliick,  snowfall  is  light  ami  i\u{'^  not  last  long. 

Storage  possibilities  have  not  been  investigated,  although  the  growing 
demand  for  water  and  for  flood  control  makes  storage  a  subject  of  con- 
siderable  importance. 

There  arc  no  o])portunities  for  water  power  development  anywhere  in 
this  basin. 

I>rainage  and  flood  control  are  subjects  of  considerable  interest  along 
this  river.  'I'be  T'nited  States  T)e|»arlment  of  .Xgricnltnre  is  making 
a  study  of  conditions  with  a  vi(;w  of  developing  a  ])lan  for  reclaiming 
and  protecting  areas  that  are  overflowed  during  floods.  Portions  of  the 
river  have  already  been  mapped  for  use  in  this  sturly. 

'^rhe  following  gaging  stations  are  ])eing  maintnined   in  this  basin:

LiTTLK  Waisash   ]Jivi:u  xkak  Ci.ay  City,  III. 

This  station  is  located  at  the  B.  &  0.  S.  W.  Ivailroad  bridge,  about 
two  miles  east  of  Clay  City,  111.  It  was  establislied  Oct.  3,  1908,  for 
the  purpose  of  obtaining  data  for  use  in  studying  problems  of  drainage 
and  Hood  control. 

Big  Muddy  creek  is  tributary  from  tlie  k'l't  bank  al)(iut  live  miles 
below  the  section.  The  total  drainage  area  above  the  gaging  station  is 
about  SOS  square  miles. 

This  station  is  at  the  toe  of  a  horseshoe  bend  in  tlie  river  and  tho 
ground  inside  the  bend  along  the  railroad  track  is  low.  During  high 
water  the  Little  Wabash  river  overflows  into  Little  Muddy  creelc,  a 
branch  of  Big  Muddy  creek,  and  in  extreme  high  water  also  overflows 
into  Big  Muddy  creek,  forming  at  such  times  a  sheet  of  water  about 
four  miles  in  width  along  the  railroad  embankment.  The  discharge  of 
the  Little  Wabash  at  the  gaging  station  during  extreme  high  water  can 
not  be  detennined  on  account  of  the  above  conditions,  for  the  flow  which 
passes  the  gaging  station  includes  some  of  the  Hood  waters  of  Big 
Muddy  creek. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation, 
and  tlie  records  are  reliable  and  accurate. 

Springs  feed  the  river  near  the  gaging  station  and  the  river  has  not 
been  known  to  go  dry  at  this  point.  The  flood  of  Feb.  8,  1909,  reached 
a  lieight  of  23.7  feet  on  the  gage.  This  station  is  maintained  principally 
to  determine  the  height  of  high  water  and  the  duration  of  floods.  On 
account  of  insufficient  data  and  poor  conditions  at  tlie  section,  the  daily 
discharge  could  not  be  determined.

investigations. 


Klni  creek  is  tribiitarv  froni  the  ri;_dit  hank  alioiit  <iiir  niih'  above  the 
station.  The  totil  drainage  area  ah<)\r  the  gaging  section  is  ahonl  1,780 
square  inilejs. 

The  datum  of  the  gage  has  not  heen  changed  sin<c  it-  iiislallal  ioii.  and 
the  records  are  accurate  and  reliable. 

The  stream  does  not  go  dry  at  this  ])oint.  This  station  is  affected  by 
backwater  from  the  Wabash  river,  '^riierefore,  the  relationship  between 
gage  heights  and  discharge  is  variable  and  hence  daily  discharges  could 
not  be  determined  from  the  data  at  present  available.

tiage  heights  Jan.  1-12  were  affected  by  ice  conditions. 


Little  Wabash  1{iveu  at  Carmi,  III. 

'I'liis  .station  is  located  at  the  hifj^lnvay  bridge  in  the  northeastern  part 
of  Carmi,  111.,  about  one-fourth  niilo  lielow  tiio  l^ij^  Four  and  L.  &  N. 
liailroad  bridge.  It  was  estjil)li.<hcd  ()(;t.  !),  IDUS,  to  obtain  data  for 
u.^e  in  studying  ilrainage.  tlood  control  and  hrvee  construction. 

.Skillet  Fork  river  is  tributjiry  on  the  right  bank  about  four  and  one- 
half  miles  abftve  the  station,  'rin-  drainage  area  al)ove  the  gaging  section 
is  about  3,000  sfjuarc  miles. 

The  relation  between  discharge  and  gage  height  at  this  station  is 
afTeeted  by  backwater  from  the  Wabash  and  Ohio  rivers,  especially  during 
extreme  floods. 

The  datum  of  the  gage  has  n-mained  unchanged  since  its  installation. 
The  records  are  accurate  and  relial)le.  but  are  atfectcd  by  backwater,  as 
stated  above. 

The  following  high  water  marks  have  been  preserved  at  tliis  station: 
187"),  gage  height  33.0  feet;  about  ISO.',,  gage  height  31  feet;  1897,  gage 


184 

height  34.5  feet;  and  1898,  gage  height  36  feet;  all  based  on  present  gage 
datum.  These  high  water  records  are  accurate  and  authentic.  There  is 
some  possibility  tliat  the  dates  may  be  slightly  in  error. 

On  account  of  backwater  conditions  at  this  station  the  daily  discharge 
cannot  be  determined  with  the  data  at  present  available.

Skillet  Fork  Eiver  near  Mill  Shoals,  III. 

This  station  is  located  at  the  B.  &  0.  Eailroad  bridge,  about  one  mile 
south  of  Mill  Shoals,  111.  It  was  established  Oct.  9,  1908,  for  the 
purpose  of  obtaining  data  for  use  in  studying  drainage  and  flood  control 
problems. 

Griffin  creek  is  tribntar}'  on  the  left  bank  about  one  and  one-lialf 
miles  above  the  station,  and  Haw  creek  is  tributary  on  the  right  bank 
about  five  miles  above  the  station.  The  drainage  area  above  the  gaging 
rjcction  is  about  912  square  miles. 

The  datum  of  the  gage  has  remained  unchanged  since  its  installation, 
and  the  records  are  accurate  and  reliable. 

This  station  is  affected  by  backwater  caused  by  floods  on  the  Wabash 
river.  Sufficient  data  are  not  available  at  present  to  enable  the  daily 
discharge  to  be  determined.
